Mid north coast firefighters are working to contain a number of bushfires in the region ahead of forecast worsening fire weather this week.
There are still around 30 fires burning from Gloucester to Taree, in the Port Macquarie area around the Nambucca and in the Clarence Valley.
Gloucester-Great Lakes Rural Fire Service Superintendent Jim Blackmore said most are now burning within control lines.
"Because we're trying to contain the fire we're actually doing quite an amount of back-burning.
"As you can appreciate the more fire you introduce the more smoke there's going to be.
"So these fires will be putting out more smoke over the next few days as we do back-burn to contain fires before conditions are expected to deteriorate.
"Worsening bushfire weather is forecast for tomorrow and it will be heating up a little bit.
"But there's a chance of some rain on Tuesday afternoon, we hope it is rain not just a dry storm."
SP Blackmore said a Bushfire Emergency in the Great Lakes is unlikely to be lifted in the near future.
"Some of the fires we've had have actually been hazard reductions that were lit up to three weeks ago," he said.
"The fires have been burning under ground, through tree roots etc and they're starting to come up again now.
"So unless we get rain, all these fires we've had will come back up in a different spot two three four weeks from now."
